You need to remove the coin, silly!
Sorry. I wanted to resist, but you tempted me ...
(Aka: Look what you made me do)


Just and armchair engineer diagnosis here: A few posts above, there is a picture of what seem to be spacers with the same pattern as the spider's interface. Maybe those have to be used? Really just guessing, I don't have the cranks.
Those photos are from BigRock crankset. I just recieved mine today and they came with spacers for spider.

From what I can tell these seem to be good quality and spindle isn't out of spec like some have reported to be the  case with other brands 24mm cranksets. I measured the q-factor to be ~146mm wich is ~1mm wider than advertised but it's still narrower than most cranksets offer.
Unfortunately I can't install them since bb I ordered is stuck in the mail sorting center. Hopefully I'm able to figure how to install them and chainline hits the spot.

You're right. I didn't realize that.

Received the cranks today. All is very well packaged, finish is great, have enough spacers and accessories to (probably) accommodate any frame. Smooth surface of the titanium axle is 92mm which is pretty much in line with my Hollowtech axle (~93 mm). The bolt that fix the axle to the crank feels dangerously light. Considering the issues mentioned in the thread I will ask my milling guy to made a proper steel bolt prior to installation. Will write back again to report how it rides and feels.

Hi, I just bought these cranks this week. I think they’re a good price and I know Bigrock makes high-quality products. They don’t come with a manual, according to the seller, but I think I’ll just follow the same steps as with the Cybrei. Have you already installed them and been able to test them? As for the bolt that holds the axle, I don’t know anyone who can make one for me — do you know where I could buy one and what it’s called, preferably a high-quality one?

The Lexon crankset that I ordered and returned from "RYET Official Store" on Aliexpress came with no specific spacers for the spider.
Two washers for mounting the pedals and three spacers (0.5mm, 1mm and 1.5mm) for adjusting gaps and chainline.
Since the gap was 5mm in my case, +2mm more on effective axle length and q-factor, I returned the crankset (I was not offered a deal on partial refund from the seller).

Meanwhile I purchased and received the Rockbros crank with 24mm spindle.
93mm effective axle length and 151mm q factor as specified, axle color is raw titanium (vs. black color of the Lexon crank).

146mm q factor is 2mm less than Shimano and approx. 5mm below most chiner carbon crankset specifications?

I just installed my BigRock cranksets yesterday. Thought I bought 165mm...accidentally bought 160mm oh well haha, I've had 165mm on a TT bike and loved it.
Will do a full review with pics tomorrow, but for now I'm very happy with them! Running Dura Ace chain rings, alignment with the spider is perfect, went together very easily and they look super slick too!

I think I found the reason for the big gap between spider and crank. It is due to the fact that the receiving end for the axle does not sit flush in the crank arm it protrudes by roughly 1 mm which equates the gap that I’m dealing with. Trying to explain that to AliExpress. But it hasn’t proven to be successful yet. I don’t think the person actually is making an effort to understand what I’m trying to explain to him or her.

I did not install them yet as I am still waiting for my groupset. You could try to find the bolt with same thread in some home repair store, such as OBI or look for a bolt with the same dimensions online. If you are in Europe I may ask my guy to make another bolt and send it to you :)

BTW 3-bolt spider from P2Max fits just fine - no play or gaps, same goes for BUCKLOS 3-bolt spider.

Well, it would be great if you can order an extra one. Let me know when you're going to do it. I live in Spain.

I’ve bought a double plate from the brand Pass Quest to see if they fit perfectly and without issues. I see that many people are happy with the quality of these and the Stone ones.

Sent you DM.

It looks like there is no issue with other mounting interfaces except Easton. Problems usually comes from the stock spider which is out of spec.
